No what I am saying is everyone that I have either read on this site or others have all said that they put in 5 psi in their bags and their truck rides like a caddy. On my 2010 F150 with 5 psi in the bags it rides like a caddy as long as I don't hit any bumps more than 1" high. This is not possible so therefore I need 12 to 15 psi in these bags for the roads that I travel on. However doing this puts the truck about an 1-1/2" to just under 2" higher on rear than what stock is. Is this a big deal probably not just wanted to know if this happens to others with the same type of truck.
Not sure if you have seen how these are installed on a 2010 F 150 but because they fit between the spring center bolt and frame they will bottom out without enough clearance. Firestone instructions on these want 5" to 7.5" height between bottom and top brackets empty or loaded. 5 psi only gives me about 3" so therefore they bottom out when driving. 12 to 15 psi gives me just over 5" so therefore no bottoming out.
It's all fine Old Coot I just wanted clarification from those that have these on a 2009 to 2013 F150 like I have and how much psi they run empty.
I guess I should have been more specific.
